METHOD OF MANUFACTURING BALL OR ROLLER CAGES FOR ANTIFRICTION THRUST BEARINGS.

Application filed October 19, 1920. Serial No. 418,039.

To aZZ'wlwmitma-g concern: 7

Be it known that I, ERNs'rI-IJALMAR VA- LODDI YVEIBULL', a subject of the King of Sweden, residing at Gottenborg, in the county of Gottenborg and Bohus and Kingdom Of'SWBClBIl, have invented a new and useful Improved Method of Manufacturing Ball or Roller Cages for Antifriction Thrust Bearings, of which the following is a specification.

The present invention refers to a method of manufacturing ball or roller cages for antifriction thrust bearings. This method of producing cages is chiefly characterized therein, that the cage is stamped or else properly pressed to the form required out of the primary material, thus avoiding all expensive and time-wasting turning and drilling-operations. A further object of the invention is an improved ball or roller cage manufactured in the way now to be. described.

The accompanying drawings show different phases of the cage metal before and after the operation and further drawings show various types of ball cages made ac cording to the invention and such as may be manufactured in this way. r

Fig. 1 is across sectional view of a piece of cage material,

Fig. 2 is a similar view through another piece of cage material of different cross sectional form,

Fig. 3 is a front elevation of a cage, and

Figs. t and 5 are sectional views through the cage along the line aa of Fig. 3, Fig. 4 thus showing the state of the cage before its perforation to get locations for the balls, while Fig. 5 shows a. completed cage with balls mounted therein.

Fig. 6 is another embodiment of a cage according to this invention'and 7 Figs. 7 and 8 respectively are sectional views along the line 72-4) transversely across the cage as in Fig. 6 under similar circumstances as regards the showing in Figs. 4; and 5 respectively. i

Fig. 9 is a sectional detail of the modi-- fied form of cage.- V

According to Figures 1 and 2, thecage materialficonsists of a piece ofmetal of rectangular, or other shape in cross section.

Out of this ring of the'holes in the cage material in order' I to procure locations for the rolling bodies may take place simultaneously with the stamping or pressing operation or immediately after the completion of such opera tion. A sectional view of the cage-subsequent to stamping as effectedin the separate stamping and punching operation will be noted upon reference to Fig. 4 wherein the numeral 3 denotes the material to be removed by another stamping or pressing process in order to obtain the locations 1 for the ballst as seen in Figs. 3 and 5. According to the modification shown at Figures 6 to 8 the ring is given the form of an H-section, and the edges '5 are bent around the balls, the latter being first en.- lodged in their locations. y

F ig. 9 shows a cage having the edges of the ball-locationsbeaten down at the point 6 and bent over the balls in order to keep.

them .in their positions.

It is evident, that primary material of any other shape may be used and other types of cages than illustrated herein may be produced according to the invention, and further that cages made in the manner (lea :7

scribed may also be used for roller-bearings or similar bearings.

What I claim is: An improved method for manufacturing 5 ball or roller cages consistingin first shaping a piece of cage material ofsuitable shape in cross section into a ring like form in plan, then stamping the ring like element in a direction at right angles to the longitudinal axis of the element to flatten the same, and punching the element at suitably spaced distances to provide openings therein. In testimony whereof I have afiixed my signature.
